Thrygg

Thrygg is the Primal of Blood Magic dragons.

When the Underworld races began to crawl up from the infernal depths of the subterranean realms, they included a new breed of dragons that were forged by the hatred and exploitation of Blood Magic. In addition to this malevolent new strain of Blood Dragons, a dragon Primal named Thrygg appeared.

Gaerrul and Thrygg, Primal of Blood Magic dragons despise each other. Hundreds of thousands of years before the Underworld Incursion, the first major skirmishes of the above and below realms occur: the dragon campaigns.
